Senior EW Direction Finding & Estimation Engineer (All Genders)

At Stark, we forge the future of European and national security through cutting-edge, AI-driven technology and unmatched engineering precision. As a premier defence technology company, our mission is clear: to equip NATO Allies and their partners  with next-generation autonomous defence platforms and advanced AI-driven software built to perform in the world’s most demanding environments.

We believe that true security stems from relentless innovation. By combining elite engineering talent with agile technology and an AI-native operational culture, Stark turns complex defence challenges into field-tested, multi-domain solutions.

WHY JOIN US

• The software and systems you work on directly protect personnel and defend European and national sovereignty.
• You will work alongside industry-leading minds on autonomous systems, advanced propulsion, and secure cyber platforms.
• We foster a fast-paced, collaborative environment where bold ideas are supported by serious R&D backing.

YOUR MISSION

You will turn our directional mesh network into a sensor. Using the same aperture that carries traffic, you will build direction finding, spectrum sensing, and GNSS-free position estimation, and prove their accuracy in the field against surveyed references. You own the error budget and the evidence, from IQ samples up to a validated position.

ABOUT THE TEAM

STARK's Electronic Warfare team is a systems-focussed engineering group delivering software-defined, mass-scalable RF solutions for autonomous systems. Combining deep domain expertise in hardware board design, thermal/ structural packaging, real-time C++ signal processing, and resilient directional mesh networking, we rapidly build field advanced EW capabilities designed to survive and operate in contested spectrum environments. 

WHAT YOU WILL DO AT STARK

• Build position estimation from the mesh itself under GNSS denial: TDOA/TOA ranging, multilateration, geometry and GDOP, the clock-synchronisation error budget, and fusion with platform navigation.
• Develop the DF and baseline spectrum-sensing chain on the directional aperture that carries traffic, running concurrently with communications.
• Own antenna calibration together with the antenna team, and keep it valid in the field.
• Own the error budget, design validation campaigns against surveyed references, and produce the evidence packs for programme milestones.

WHAT YOU BRING TO THE MISSION

• You have measured DF accuracy against real signals and done localisation with an explicit geometry and error budget. Practical experience is what counts here, not GNSS integration or theory alone.
• You have run measurement campaigns validated against a surveyed reference.
• You have calibrated an antenna array yourself.
• You work comfortably from IQ data and channel-level observables upward.

NICE TO HAVE

• A background in direction finding, radar, or SIGINT, whether from industry, a research institute, or space-based SIGINT.
• Publications with a real measurement section.
• Kalman filter or factor-graph estimation.
